6.2 DHW temperature control

DHW temperature control

There are various types of DHW temperature control used in
Danfoss substations.
DHW temperature should be adjusted to 45-50 °C, as this provides
optimal utilisation of DH water. At DHW temperatures above 55 °C,
the possibility of lime scale deposits increases significantly.

6.2.1 RAVK controller

RAVK controller (25-65 °C). The temperature setting is as follows:
1 = 25 °C
2 = 35 °C
3 = 45 °C
4 = 55 °C
5 = 65 °C

The values are intended as a guide.

Thermostatic control

DHW temperature is adjusted as follows:
To increase temperature, turn the handle on the thermostatic
controller to select a higher number.
To decrease temperature, turn the handle on the thermostatic
controller to select a lower number.

6.2.2 AVTB controller (20–60 °)

The temperature setting is as follows:
1 = 20 °C
2 = 35 °C
3 = 50 °C
4 = 60 °C
5 = 70 °C

The values are intended as a guide.

The AVTB operates at its best at DH supply temperatures of up to
90 °C.

Thermostatic control

DHW temperature is adjusted as follows:
To increase temperature, turn the handle on the thermostatic
controller to select a higher number.
To decrease temperature, turn the handle on the thermostatic
controller to select a lower number.
